Default boundary condition
Lu Zhang
Posts: n/a
hello, I am having a problem with choosing the right boundary condition for a gas phase aerosol reactor. I have no problem with the inlet, where the gas comes in at fixed mass flow rate. But on the outlet bondary, where a mechanical pump is pumping gas out to maitain the pressure inside of the reactor at 1atm, I am not sure what kind of boundary condition should I apply. Also, the density is not a constant in the reactor (ideal gas law). Thank you.
